I am using ir with microsoft cinema, moto G3, and 12' telescoping pole to film tight view of inside run or individual periods. It has been reliable performer. over past 2 seasons. 720p resolution is more then adequate. It provides lots of features and settings; most of which I do not use. Only negative is that it does not support my video capture device like some of the other products do. this is not a major issue for me so I will continue to use it due to reliability and performance. there few features that would make it even more useful: 1. record zoomed image 2. zoom while recording 3. +/- zoom button never the less, still a great product.

My stuff: Moto X4 32g, Android 9 latest update 2/1/2019 Web camera I tried is the Logitech C615. This only works with this camera at the VGA resolution :640 x 480. Attempting to change resolution via menu does not work. Always in VGA res. Menu items disappear too quickly to set sometimes. Can't change the frame rate or resolution. I wanted this webcam to take pictures inside of a string bass at 1080p but couldn't do it. I don't know what web cam will work with this app. This may just be an incompatible combination of app and camera.

Connects OK but then in permanent state of 'detecting' and nothing happens. Nice settings menu if I could get it to work! Can specify where to save output too which is a nice feature. Refund please.
